BEBNHARD G. CARLSjSON, OF LOS ANGELES, CALIFORNIA.

GAS-REGULATOR.

Application filed April 19, 1921.

To all whom it may concern:

Be it known that I, BERNHARD G. CannesoN, a citizenof the United States,and a resident of Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented new and useful Improvements in GasRegulators,of which the following is a specification.

This invention relates to, and has for its main object, the provision ofan efiicient, simple, and compact regulating device, attachable to theinstrument board of an automobile for regulating the mixture of fuelsupplied to the motor.

It is an object of my invention to provide in a device of the characterstated, visible means for indicating on a suitable dial or surface, thecharacter of a mixture required for obtaining the most eflicient andeconomical operationof the motor under diiferent In other well knownforms of vice conveniently positioned with respect to the driver of the'automobile. Such devices,

however, are generally unsatisfactory, for

the reason that the majority of automobile drivers are inexperienced,untechnical, and

are not versed in the properties or characteristics of the fuel,andtherefore do not properly use or operate the regulating means forobtainingthe best, with a minimum con sumption of fuel.

In many cases also, because of ignorance of; the exact requirements ofthe motor for obtaining the best results, orfor the reason the operatorforgets the proper position of the regulator for greatest efliciency,the device is not used at all, orif used, it is improperly operated,causing the above circumstances. I haveprovided a means for regulatingthe fuel supply which is adapted to be connected in a suitable mannerwith the needle valve of the carbureter for regulating the volume offuel admitted into the intake manifold of the motor, which in com-;

bination with said specific dial, of structure and arrangement of parts,whereby the exact requirements of the motor, under varying conditions,may be visibly indicated so that a novice or an inexperienced driver maythoroughly understand the operation of the Specification of LettersPatent.

device, and regulate the same in a proper manner and to a proper extentfor obtaining the best results.

With these and other objects in view, which may appear asthe'description progresses, I have illustrated one practical embodimentof my device, comprising the essential features of my invention andsubject to modification within the scope of the appended claims, in theaccompanying drawings, in which:

Figure l is a face view of my indicating device.

Fig. 2 is a side view of the same.

7 Fig. 3 is a section of the same, on line 33 of Fig. 1.

Fig. 4 is a fragmentary sectional the same, on line 4-4 of Fig. 3.

Fig. 5 is an elevation, showing the operative connection between mydevice and the carbureter, for carrying out the objects of plan of y minvention, as hereinbefore stated.

y device consists primarily, of a dial D and a manually operatedindicator I, adapted to be suitably attached to the instrument board Bof an automobile. The dial D has an annular flat flange portion (Z, witha semispherical central portion 03 integrally formed therewith,andhaving arcuate slots S and S formed at diametrical points between thedial portion at and central portion d. The indicator I comprises a stemA which hasa handle II either formed thereon or suitably attachedthereto and provided with a bearing portion a, which is rotatably heldin a boss b formed on the interior of the central portion (5 of thedial. The portion A of the handle stem is preferably squared and isadapted to receive the central portion z of the indicator I.

Said indicator has a pointer P which extends through the slot S of thedial and is movably disposed over a segment of the portion d of thedial. The opposite end P is preferably of the form of an automobile andis so positioned that the wheels W, W, of the automobile will touch theouter edge of the sphere orglobe on the dial, as shown in Fig. 1.

I have marked the central portion d', which is semi-spherical withmeridians and parallels, such as would be found on aglobe or sphere,(with the meridians and parallels of the earth marked thereon), and Ihave provided on the upper periphery of this.

spond with the work done by the motor.

For instance, frequently by retarding the spark and providing a richermixture of the fuel on grades,the motor will give more satisfaction, andprovide more power for the car. Thus, I have shown on the sphericalportion 0K of the indicator, the words Up hill at the left extremity ofthe slot S, and as shown in Fig. 1, when the portion P of the indicatoris moved into the position shown in'broken lines, toward the leftextremityof the slot S and on the radial lines of the'words Up hill theoperator of the car will understand that the movement of the automobileinto the position jshown in broken lines in Fig. 1, will indicate andregulate the mixture of fuel to the proper extent, and theautomobilewill be in an inclined position. In such event, when runningon the level ground, the portion P of theindicator will be substantiallyon a horizontal line and above the word Level and when running downhill, the portion P will be moved 'tothe right over the words Down hill.The movement of the indicator I is accomplished by means of the handleH. In many cases atmospheric conditions retardthe regulation of themixture, and in order' that'thefuel supply may be properly regulated, insuch event, I'have provided, adjacent the top of the lower slot S, agraduating scale of figures, 1, 2, 3, 4, 5, etc, and in some cases, orat the will of the driver of r a vehicle, the extent of movement of theindicator I may be best determined by moving 4 the indicator I so thatthe pointer P will register with certain of the numbers 1, 2, 3, 4, 5,etc. 7

I In addition to the indicia and indicating means described above forregulating the V movement of the indicator to correspond tothe'dilferent requirements of the motor, I may provide on the lowerportion of the dial d at the left of the center, the words Iiean, Highspeed, Easyrun. In the center of the dial, midway between the extremesof movement of the pointer P, I may provide the word Medium, and at theright extreme movement of said pointer, I

may provide the words, Rich, Low speed, Hard pull. Thus, willbe'indicated on the dial both graphically and otherwise, to meet allconditions and for the benefit of both experienced and inexperiencedoperators of vehicles, just what should be the character of the mixtureoffuel for all conditions and requirements of the motor It is a factalso, especially on Ford automobiles, that an adjustment of the sparklever is necessary, or desirable, for obtaining the best results underdifferent conditions, and circumstances, and I may provide, therefore,on the lower central portion of the dial (1 of my regulator device,suitable indicia or instructions to the operator for the regulation ofthe spark lever to correspond with the regulation of the fuel supply.

As shown in Fig. 5 the stem A of the indicator I may be connected withthe needle valve V of the carbureter G by means of a bell crank lever Land a rod R connecting said lever with the valve operating lever L onthe carbureter, or otherwise. The specific means of connection betweenmy regulator and the carbureter valve being i1n1naterial, as it will beunderstood that all carbureters are differently constructed and requiredifferent types of connecting mecha nism.

According to recent tests made for the purpose of ascertaining thevolume of coinbustible gases discharged through the exhaust from trucksand pleasure automobiles under average working conditions, it has beenfound that thirty per cent. of the fuel now used by automobiles in theUnited States is wasted through improper adjustment of the carbureter,thus causing incomplete combustion, and it is with a view to correctingthese conditions so far as pos sible, that I have provided means foraccurately adjusting the carbureter to a proper extent, corresponding tothe requirements of the motor, and whereby the spark lever of the motormay be correspondingly adjusted for obtaining the most economicalconsumption of fuel and the best results generally.

[111 most modern types of automobiles, the mechanism provided foradjusting the carbureter to change the character of the fuel mixture areof such character that it is impossible for an operator to knowdefinitely which way to operate the device for obtaining desiredresults, and frequently when an operator becomes acquainted with the useof such device, he may forget the exact position to which the carbureteradjusting lever or arrangement should be moved for certain conditions ofservice.

In my device, herein disclosed it will be noted that I have provided acomprehensive means for clearly denoting the proper position for thecarbureter adjusting device under all conditions.

What I claim is:

1. A gas regulator for motor propelled vehicles, including a dial havinga semispher'ical central portion with indicia thereon, for visiblyindicating the proper movement of the regulator and a flange surroundingsaid portion and also having indicia thereon, and an indicator pivotallymounted on said central portion and movable over the face of said dialfor registration with said indicia, as described. a
